So I have my view:
def home_page(request):
form = UsersForm()
if request.method == "POST":
form = UsersForm(request.POST)
if form.is_valid():
form.save()
c = {}
c.update(csrf(request))
c.update({'form':form})
return render_to_response('home_page.html', c)
my forms.py:
class UsersForm(forms.ModelForm):
class Meta:
model = Users
widgets = {'password':forms.PasswordInput()}
def __init__(self, *args, **kwargs):
super( UsersForm, self ).__init__(*args, **kwargs)
self.fields[ 'first_name' ].widget.attrs[ 'placeholder' ]="First Name"
self.fields[ 'last_name' ].widget.attrs[ 'placeholder' ]="Last Name"
self.fields[ 'password' ].widget.attrs[ 'placeholder' ]="Password"
and my template:
<html>
<body>
<form method="post" action="">{% csrf_token %}
{{ form.first_name }} {{form.last_name }} <br>
{{ form.password }} <br>
<input type="submit" value="Submit Form"/>
</form>
{% if form.errors %}
{% for field in form %}
{% for error in field.errors %}
<p> {{ errors }} </p>
{% endfor %}
{% endfor %}
{% for error in form.non_field_errors %}
<p> {{ error }} </p>
{% endfor %}
{% endif %}
</body>
</html>
Now, keep in mind that before I split the form field, my form just looked like this:
<form method="post" action="">{% csrf_token %}
{{ form }}
<input type="submit" value="Submit Form"/>
</form>
and if the form had a problem (like if one of the fields was missing) it would automatically give an error message. After I split up the form fields in the template (made {{ form.first_name }}, {{ form.last_name }} and {{ form.password }} their own section) it stopped automatically giving error messages. Is this normal?
But the main problem is, how come my {{ if form.errors }} statement is not working / displaying error messages if there are error messages? For example, if I purposely not fill out a field in the form and I click submit, the database does not get updates (which is a good thing) but it does not give any error messages. Any idea why?
I also tried remove the {{ forms.non_field_errors }} and tried to return just field errors like so:
{% if form.errors %}
{% for field in form %}
{% for error in field.errors %}
<p> {{ errors }} </p>
{% endfor %}
{% endfor %}
{% endif %}
but it still doesn't work.

I found the mistake (typo).
The snippet should be:
{% if form.errors %}
{% for field in form %}
{% for error in field.errors %}
<p> {{ error }} </p>
{% endfor %}
{% endfor %}
{% endif %}
I had errors instead of error.

you have to send your form context again if is_valid() isn't true,
if form.is_valid():
return redirect('/user/contact/')
else:
return render(request, 'users/contact.html', context={'form': form})
because your errors will display in your form else: it will return ValueError
